Definitions

  • the invention comprises an optical cable having, within an outer sheath, at least three longitudinally extending strength members with at least one interstitial space between them in which there is loosely accommodated a package comprising a plurality of optical fibres.
  • the optical fibres may be in the form of a stranded bundle, a ribbon, a plurality of ribbons stacked one upon the other, or other convenient configuration.
  • the fibre package is contained within a tube dimensioned to allow a degree of transverse movement of the fibres within it, the tube being preferably filled with a water blocking substance such as grease.
  • a water blocking substance may also be incorporated in the interstices between adjacent strength members, and between the strength members and the outer sheath.
  • strength members of circular cross-section this is conveniently achieved with four or five strength members, these preferably being formed of glass reinforced plastic or other suitable high modulus material stranded together in a helical configuration.
  • optical fibres are conveniently accommodated in a central channel surrounded by the strength members.
  • this illustrates a cable comprising four circular sectioned strength members 1 of glass-reinforced plastics material, each having a diameter of approximately 5 mm stranded together around a central filler 2 of polyethylene having a diameter of approximately 2 mm, and surrounded by a close fitting polyethylene or other polymer sheath 3 having a wall thickness of approximately 1.5 mm.
